Insane quality and fits you so nice, I love it !!
So beautiful and chic!! Would love to get them in every colour if the sizes are available for me
I didn’t realize I would love this dress so much but the material is amazing! It fits me in all the right places without overly clinging to my body. Oh Polly has such great quality clothes. I’m 5”5 and 185lbs. Would say the medium fits very true to size.
